MARBLE-CUTTING MACH|NE.

SPECIFICATION forming part of Letters Patent No. 416,164, dated December 3, 1889.

Application filed January 12, 1889. Serial No. 296,036. (No model.)

' chines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for cutting and shaping marble, slate, or any soft stone; and it consists in certain mechanical devices hereinafter more fully described and pointed out in the claims.

Figure 1 is an elevation view of the ma chine, showing parts thereof in vertical sec tion. Fig. 2 is a plan or top view of the machine and shows in section a portion of the frame. Figs. 3, 4, 5, 6, '7, and 14: are views showing more in detail various parts of the mechanism. Figs. 9, 10, 11, 12, 13, and 15 are views showing more in detail the cuttingtools used; and Fig. 8 is a plan view of gearing, showing how the power is applied which produces the movement of the Various parts, and also showing in section a portion of the frame.

A, Figs. 1 and 1, is the bed or frame of the machine, formed of two parts bolted together, one of which turns upward, forming an arm for the purpose of supporting the driving and cutting mechanism, while upon the other rests that portion of the mechanism which is designed to carry the material to be shaped.

The power which moves the various parts of this machine is communicated from an engine in the usual way by means of a belt passing over one of the pulleys S, the large or small one being used, according to the rate of speed desired. These pulleys are provided with the usual clutches for throwingthem in or out of gear with the driving mechanism, and when either is in gear therewith it turns the shaft T, which is supported by arms extending upwardly from the arm portion of the bed or frame A. At the extremity of the arm portion of A a perpendicular shaft Wis supported and is capable of adjustment to any desired height by any suitable means.

This shaft receives its power from the shaft T by means of the miter-gears V.

Various cutting-tools, depending upon the character of the design to be produced, are employed in the use of this machine; but they may all be divided into two classesvertical or horizontal, according to theposition in which they are used.

The vertical tools are connected by any suitable means to the lower end of the shaft' screws will come in contact with the edges of l the tools and bind them. The ring cis normally slightly smaller than the head on, but is placed thereon when hot, thus being held firmly by the shrinking of the metal. when it becomes cool.

The horizontal tools consist of knives h, which are set in the sides of the head. The head is mounted on a spindle 6, held in two downwardly-proj ectin g arms of the removable holder n, Fig. 14, and is revolved by means of the power received from the vertical shaft and communicated through the gears d, Fig. 1. The head of the horizontal tool is formed of two collars, one surrounding the other. The outer one is formed in six parts or segments of a circle a a a &c., Fig. 15, two of which, a and a, are each one-quarter of the whole, and are fastened on the inner collar on opposite sides thereof by means of screws passing through the flanges g, Fig. 9, of the inner collar and the segments themselves. The four knives h are placed against the four radiating sides of these segments, and in each of the two opposite spaces between the knives are placed two of the other and smaller segments of the outer collar-in the one a and a and in the other a and a. By this arrangement the four knives are placed equidistant from each other. They are held in this position by the tapered screws 2', one of which passes between the adjoining sides of a and d and the other between those of a and a, thereby causing all the parts to bind. The screws enter a sufficient distance into the inner collar to hold the parts firmly. The flanges g on. the inner collar prevent anylongitudinal movement of the parts. v

That portion of the machine designed to carry the material to be shaped is provided with two carriages B O and a table D. The lower carriage B moves in ways to or from the operator along and by means of the screwshaft. L. The upper carriage 0, supported on B, moves in ways at, right angles thereto by means of the screw-shaft N. The table D is supported on the carriage C and moves only therewith. The screw or main shaft L receives its power to revolve by the pulleys M when in gear therewith, a straight belt running over one and a crossed belt over the other to the pulleys R on the shaft T, heretofore mentioned, thereby enabling the operator to reverse the motion of the shaft L at will. The shaft N receives its power by means of the spur-wheels t, Fig. 8, and the miter-gears Q] from the shaft P, which receives its power from L by means of the spurwheels On the upper table are pivoted at E and E respectively, Figs. 2 and 5, a disk E, Fig. 6, and a quadrant F, Fig. 7, each of which is provided on the under side with a rack near the outer edge. Beneath the table D there is a lever Z, pivoted on the shaft G, and having two wheels G G2 geared together. By turning the lever Z to the right or left G2 can be geared with the rack on either the disk or quad ant, as may be desired. The shaft G extends through the carriage C, and beneath said carriage is pro- Vided with a worm-wheel H, which engages with the screw on the shaft I. Power is communicated to the shaft I from the main shaft L by the gears w, shaft J, miter-gears s, shaft K, and gears 19, and either the disk or quadrant may be slowly turned at will whenever G is in gear with one or the other. Bymeans of this mechanism for carrying the material to be operated upon it is plain that the operatorcan not only bring any portion of the material directly under and in connection with the cutting tools and can cause the material to move slowly along in any direction against said tools, but also, if the material be placed upon the disk it can be cut in the form of a circle, or if upon the quadrant the corners of a rectangular piece can be cut to that form. It will be observed that when this ltSt-ll1e1ltioned operation is performed the machine once started will cut an exact quarter of a circle if the material be first properly adj usted on the quadrant, for the moment the quadrant has turned the material to the distance of ninety degrees it will cease to move farther, because the turning power will then have reached the end of the rack on the quadrant and the quadrant willstop. On the table D there is also a lathe A A which is operated by means of the spur-wheels B B shaft 0, worm-wheel D screw on shaft K, and spurwheels 19, one of which is on the main shaft L. The lathe isused for turning posts, vases, columns, &c., and if the carriage C, on which the table D rests, be in motion at the same time that the lathe is operated a spiral may be out in or various other forms of ornamentation given to the article held in the lathe.

Each of the shafts L, K, or P is provided with one or more clutches w, for throwing the various parts of the mechanism in or out of gear with the pulleys M, and either may be turned by hand, when desired, by removable cranks.

A circular saw f can be put on the spindle e in the place of a horizontal tool whenever it becomes desirable to do so.
